The embodiments described herein with respect to thedrawings are illustrative and graphical, and are used for providing abasic understanding of the present application. The embodiments of thepresent application should not be interpreted as limitations to thepresent application.

In some embodiments of the present application, an electronic vaporizerdevice is also referred to as an electronic cigarette, the electronicvaporizer device including an electronic vaporizer device body and anelectronic vaporizer, the electronic vaporizer device body is alsoreferred to as a cigarette rod, and the electronic vaporizer is alsoreferred to as a is cartridge. In some embodiments of the presentapplication, the cartridge and the cigarette rod are separate structuralcomponents, and the cartridge is connected to the cigarette rod in apluggable manner. The cartridge is engaged with the cigarette rod toform an electronic cigarette. In some embodiments of the presentapplication, the cartridge and the cigarette rod are integrally formedstructural components.

FIG. 1 is a schematic block diagram of an electronic cigarette accordingto some embodiments of the present application. The electronic cigarette10 includes a cartridge 11 and a cigarette rod 12. The cartridge 11includes a heating circuit 111 for heating e-liquid or similarvaporizable substances stored in the cartridge 11 into a vaporizationstate, for the user to inhale or smoke. The cigarette rod 12 includes amain control circuit 123, an indicator light 126, and a battery 127. Thebattery 127 serves as a power supply configured to supply power to theelectronic cigarette 10 when the electronic cigarette 11 is inoperation.

In some embodiments of the present application, the cigarette rod 12further includes a charging circuit 128. The charging circuit 128 isconfigured to connect to an external power supply to charge the battery127. The charging circuit 128 includes a USB type-C (a Universal SerialBus Interface) interface that is connected to the external power supplyvia the USB type-C interface to charge the battery 127. It should benoted that a specific form of the charging circuit 128 is not limited tothe foregoing description.

FIGS. 2A-2B are schematic diagrams of a cartridge 11 and a cigarette rod12 in an engaged state of an electronic cigarette 10 according to someembodiments of the present application. As shown in FIG. 2A, thecartridge 11 and the cigarette rod 12 are in a disengaged state. Asshown in FIG. 2B, the cartridge 11 and the cigarette rod 12 are in anengaged state. The cartridge 11 is inserted into the cigarette rod 12 toform the engaged state in FIG. 2B. Because the cartridge 11 itself hasresistance, when the cartridge 11 is inserted into the cigarette rod 12and engaged with the is cigarette rod 12, the cartridge 11 divides avoltage. An output level of a circuit connected to the cartridge 11 isdetected to determine whether the cartridge 11 is engaged with thecigarette rod 12. Specifically, when a main control circuit 123 detectsthat the output level of the connection circuit is a high level, thecartridge 11 and the cigarette rod 12 are in a disengaged state. Whenthe main control circuit 123 detects that the output level of theconnection circuit is a low level, the cartridge 11 and the cigaretterod 12 are in an engaged state. The main control circuit 123 drives anindicator light 126 to operate in an alerting mode when the cartridge 11and the cigarette rod 12 are detected to be in the engaged state. Thealerting mode is: the indicator light 126 is bright and then graduallygoes out, so that the user can be notified that the cartridge 11 and thecigarette rod 12 has been engaged and can be used normally. In someembodiments of the present application, the main control circuit 123 mayalso determine that the cartridge 11 and the cigarette rod 12 have notbeen engaged when the output level of the connection circuit is detectedto be a low level, and determine that the cartridge 11 and the cigaretterod 12 have been engaged when the output level of the connection circuitis detected to be a high level.

It should be noted that, in the embodiment of the present application,the high level and the low level are different logic levels havingrelative voltage values. When the voltage is between V1 and V2, thelevel is high, and when the voltage is between V3 and V4, the level islow, where V1 is not less than V4. For example, 0-0.25 V may bepredetermined as low level, and 3.5-5 V are predetermined as high level,but is not limited thereto and may be determined according to practicalconditions.

In some embodiments of the present application, as shown in FIG. 1, thecigarette rod 12 further includes a motor 122. The main control circuit123 controls, when the cartridge 11 and the cigarette rod 12 aredetected to be in an engaged state, the motor 122 to operate in analerting mode, that is, the motor 122 vibrates after a time T1. Forexample, the motor 122 may be controlled to vibrate once every 0.5 safter the cartridge 11 and the cigarette rod 12 are in an engaged state,and the vibration time is 40 ms. The time and manner for vibration ofthe motor 122 are not limited to the foregoing description, and may beselected according to practical conditions. The motor 122 is vibrated toinform the user that the cartridge 11 and the cigarette rod 12 have beenengaged and can be used normally. It should be noted that both the motor122 and the indicator light 126 belong to the alerting device foralerting, in different modes, the user that the electronic cigarette isoperating in different states. The alerting device may also includeother alerting devices, for example, a display screen may be provided inthe electronic cigarette 10 to alert the user by using an icon, adynamic image, a text, or the like. In some embodiments of the presentapplication, the alerting device further includes an acoustic generatorand a vibrator.

In some embodiments of the present application, the cartridge 11 furtherincludes an authentication circuit 112. When the cartridge 11 and thecigarette rod 12 are in a disengaged state, the main control circuit 123is non-electrically connected to the authentication circuit 112. Whenthe cartridge 11 and the cigarette rod 12 are in an engaged state, themain control circuit 123 is electrically connected to the authenticationcircuit 112. The authentication circuit 112 includes a resistor thatindicates flavor information of the cartridge 11. When the cartridge 11and the cigarette rod 12 are in an engaged state, the foregoingconnection pin of the main control circuit 123 and the resistor form anelectrical connection loop. Depending on different resistance values ofthe resistor in each cartridge 11, the main control circuit 123determines that a level of the connection pin corresponding to theresistor, and determines the cartridge 11 of different flavors accordingto different levels. For example, when the resistance is 2 ohms, itindicates that a grapefruit-flavor cartridge 11 is engaged with thecigarette rod 12. When the resistance is 4 ohms, it indicates that amint-flavor cartridge 11 is engaged with the cigarette rod 12. It shouldbe noted that a resistance value of a specific resistor and the flavorof the corresponding cartridge 11 are not limited thereto, which can bedetermined according to practical conditions.

In some embodiments of the present application, as shown in FIG. 1, thecigarette rod 12 further includes an airflow sensor 121. The airflowsensor 121 is electrically connected to the main control circuit 123. Insome embodiments of the present application, the main control circuit123 enables the airflow sensor 121 when the output level of theconnection circuit is detected to be a high level. In some embodimentsof the present application, the main control circuit 123 enables theairflow sensor 121 when the output level of the connection circuit isdetected to be a low level. Enabling the airflow sensor 121 may refer tosupplying power to the airflow sensor 121, or may refer to initializingthe airflow sensor 121 to prepare the airflow sensor 121 for normaldetection.

In some embodiments of the present application, when the cartridge 11and the cigarette rod 12 are in an engaged state, the user can smoke orinhale normally. The airflow sensor 121 detects an airflow change whenthe user performs a vaping action. When the airflow sensor 121 detectsthe airflow, that is, when the air flows or changes, the airflow sensor121 outputs a high level, that is, it indicates that the user is vaping.In this case, the main control circuit 123 controls a heating circuit111 to perform heating to vaporize the e-liquid. When the airflow sensor121 does not detect the airflow, that is, when no air flows or changes,the airflow sensor 121 outputs a low level, that is, it indicates thatthe user has stopped vaping. Then the main control circuit 123 controlsa heating circuit 111 to stop heating. The main control circuit 123records a start time t2 at which the high level is generated when thelow level is detected to be converted into the high level, and records astart time t3 at which the low level is generated when the high level isdetected to be converted into the low level next time. A time T2=t3−t2for which the user takes one puff, where t3 is greater than t2. The maincontrol circuit 123 performs counting and increases a count value C1when T2 is greater than a preset threshold t4, for example, the countvalue may increase by 1, t4 may be set to 1 s, but is not limitedthereto. When the count value C1 within a preset time T3 is greater thana preset threshold n, the main control circuit 123 drives the is motor122 and the indicator light to operate in the alerting mode. Thealerting mode is: the motor 122 vibrates. For example, when the countvalue C1 is greater than 15 within 10 minutes of T3, the main controlcircuit 123 may drive the motor 122 to vibrate once for one second afterthe 15th puff with a vibration time of 40 ms, thereby effectivelyalerting the user to control the vaping amount and preventing excessivevaping.

In some embodiments of the present application, the airflow sensor 121may also output a low level when the airflow is detected, and outputs ahigh level when no airflow is detected. The main control circuit 123 maydetermine whether the user is smoking according to level informationthat has different logic levels output by the airflow sensor 121, andthe specific determining manner is not limited to the foregoing.

In some embodiments of the present application, the main control circuit123 disconnects the power supply from the battery 127 to the heatingcircuit 111 when T2 is greater than t5, so that the heating circuit 111stops heating. For example, the control circuit 123 disconnects thepower supply from the battery 127 from the heating circuit 111 when T2is greater than 5 s, so that the heating circuit 111 stops heating. Inthis way, the user can be prevented from smoking excessively.

In some embodiments of the present application, as shown in FIG. 1, thecigarette rod 12 further includes a memory 124 and a wirelesscommunication circuit 125, both the memory 124 and the wirelesscommunication circuit 125 being electrically connected to the maincontrol circuit 123. The memory 124 may be configured to storeinformation and be read and written. The memory 124 stores smokinginformation, the smoking information including an ID of the cartridge11, the number of puffs, smoking time, and the like.

The wireless communication circuit 125 is used for performing wirelesscommunication. The wireless communication may use one or more of thefollowing modes: Bluetooth, Wi-Fi, the 3rd generation (3G) mobilecommunication technology, the 4th generation (4G) mobile communicationtechnology, the 5th generation (5G) mobile communication is technology,near field communication, ultrasonic communication, ZigBee (ZigBeeprotocol), radio frequency identification (RFID), and the like. The maincontrol circuit 123 interacts with an intelligent terminal through thewireless communication circuit 125. The intelligent terminal includes amobile phone, a computer, an intelligent wearable apparatus (forexample, an intelligent watch), a tablet, and the like.

In some embodiments of the present application, as shown in FIG. 3, thecigarette rod 12 further includes an acceleration sensor 129, theacceleration sensor 129 being electrically connected to the main controlcircuit 123. In some embodiments of the present application, the maincontrol circuit 123 enables the acceleration sensor 129 when the outputlevel of the connection circuit is detected to be a high level. In someembodiments of the present application, the main control circuit 123enables the airflow sensor 129 when the output level of the connectioncircuit is detected to be a low level. Enabling the acceleration sensor129 may refer to supplying power to the airflow sensor 129, or may referto initializing the acceleration sensor 129 to prepare the accelerationsensor 129 for normal detection.

In some embodiments of the present application, the main control circuit123 obtains acceleration information of the acceleration sensor 129, andenables the wireless communication circuit 125 when an accelerationvalue included in the acceleration information is greater than a presetthreshold al. The acceleration value includes at least one of anacceleration value in an X-axis direction, an acceleration value in aY-axis direction, or an acceleration value in a Z-axis direction in acoordinate system. The acceleration sensor 129 is a G-sensor (a gravitysensor), but is not limited thereto. A case that the acceleration valueis greater than the preset threshold al may indicate that the user isshaking the electronic cigarette 10. For example, when the wirelesscommunication circuit 125 includes a Bluetooth module and performswireless communication using the Bluetooth module, the main controlcircuit 123 enables the Bluetooth module when the obtained accelerationvalue is greater than the preset threshold al, and sends a broadcastsignal through the Bluetooth module. In addition, the main controlcircuit 123 is further configured to operate in a fourth driving modewhen the obtained acceleration value is greater than the presetthreshold al and the count value C1 is increased, and the fourth drivingmode is: controlling the indicator light 126 to flash 15 times, toremind the user that the Bluetooth mode of the electronic cigarette 10is enabled. In addition, if the user performs the shaking action again,the indicator light 126 will flash again 15 times. In this case, theuser may perform Bluetooth matching with the electronic cigarette 10through the intelligent terminal, and perform Bluetooth communicationafter the matching is performed successfully. The main control circuit123 may send or transmit the smoking information stored in the memory124 to the intelligent terminal through Bluetooth communication. Adedicated application (APP) of the intelligent terminal performs dataanalysis according to the received smoking information to better guidethe user to control smoking, reduce or quit smoking.

In some embodiments of the present application, the authenticationcircuit 112 includes an encryption chip (not shown in the figure). Theencryption chip stores encrypted data information of the cartridge 11,the data information including a unique ID number, a flavor of thecartridge, an amount of tar of the cartridge, and the like. The maincontrol circuit 123 includes a decryption module corresponding to theencryption chip, and the decryption module includes a decryption chip.The decryption module is configured to decrypt the encrypted informationwhen the cartridge 11 and the cigarette rod 12 are in an engaged state,send or transmit decryption success information when the decryption issuccessful, and send or transmit decryption failure information when thedecryption fails. Upon receiving the decryption failure information, themain control circuit 123 disconnects the battery 127 from the heatingcircuit 111. If the decryption success message is received, the maincontrol circuit 123 drives the indicator light 126 to flash three timesand drives the motor 123 to vibrate for a short time three times. Themain control circuit 123 enables the Bluetooth module to transmit thebroadcast signal after successfully decrypting the encrypted datainformation obtained from the encryption chip.

FIG. 4 is a schematic diagram of interaction between an electroniccigarette 10 and an intelligent terminal according to some embodimentsof the present application. An intelligent terminal 201 turns on theBluetooth and matches the electronic cigarette 10, and receives the datainformation sent or transmitted by the electronic cigarette 10 after thematching is successful. The intelligent terminal 201 sends or transmitsthe foregoing data information to a server 202, and the server 202 isconfigured to send analyzed and processed information about theelectronic cigarette 10 to the intelligent terminal 201. The intelligentterminal 201 displays the data information of the cartridge 11 by thededicated APP, including information such as the flavor of thecartridge, the number of puffs per day, the number of puffs per week,the number of puffs per month, the number of accumulated puffs, and anamount of remaining e-liquid, which are displayed as a graph. The amountof remaining e-liquid may be obtained according to the number ofaccumulated puffs for the cartridge 11.

In some embodiments of the present application, when the electroniccigarette 10 and the intelligent terminal 201 are in a Bluetoothconnection state, the “stop heating” touch control widget on thededicated APP is activated by the user, and the intelligent terminal 201obtains the “stop heating” instruction, and transmits the “stop heating”instruction to the main control circuit 123 via a Bluetoothcommunication link. Upon receiving the “stop heating” instruction, themain control circuit 123 disconnects the power supply from the battery127 to the heating circuit 111, and the heating circuit 111 stopsheating. Even if the airflow sensor 121 detects the airflow and outputsa high level, that is, the user is vaping, the heating circuit 111 isnot powered either; that is, the heating circuit 111 cannot heat thee-liquid.

In some embodiments of the present application, the electronic cigarette10 is also prohibited or forbidden from being used in a non-smokingarea. The intelligent terminal 201 has a locating or positioningfunction. When the user carries the intelligent terminal 201 and theelectronic cigarette 10 into a virtual geofence 301, as shown in FIG. 5,the intelligent terminal 201 and the electronic cigarette 10 are in aBluetooth connection state. The intelligent terminal 201 automaticallyreceives a notification of “entering the fence”. The intelligentterminal 201 sends a “no smoking” instruction to the electroniccigarette 10 when determining that a current location is within thegeofence 301, that is, belongs to the non-smoking area. The main controlcircuit 123 of the electronic cigarette 10 is switched to the “nosmoking” mode upon receiving the “no smoking” instruction, that is,disconnects the electrical connection between the battery 127 and theheating circuit 111, and the heating circuit 111 is prohibited orforbidden from enabling the heating function, and does not respond tolevel information output by the airflow sensor 121. In other words, evenif the airflow sensor 121 detects the airflow and outputs a high level,that is, the user is vaping, the heating circuit 111 is not poweredeither, that is, the heating circuit 111 cannot heat the e-liquid.Therefore, even if the user performs the vaping action on the electroniccigarette 10 after entering the non-smoking area, the electroniccigarette 10 would not heat the e-liquid to form an atomized state, sothat the user can be effectively prevented from illegally smoking.

The geofence 301 may be a virtual geographic boundary defined using anygeofence technology, for example, an airport, a gas station, a mall, andthe like. In addition, if the intelligent terminal 201 enters thegeofence 301 and the intelligent terminal 201 determines that thegeofence 301 does not belong to the non-smoking area, the “no smoking”instruction would not be sent to the electronic cigarette 10.

Specifically, as shown in FIG. 6, the main control circuit 123 includesa switch 1231 and a switch 1232. The switch 1231 and the switch 1232 areconnected in series and are disposed in a circuit between the battery127 and the heating circuit 111. When both the switch 1231 and theswitch 1232 are switched or turned on, the battery 127 supplies power tothe heating circuit 111 normally, causing the heating circuit 111 toheat the e-liquid. When at least one of the switch 1231 and the switch1232 is switched or turned off, the battery 127 and the heating circuit111 are in an is open circuit state, and the heating circuit 111 wouldnot perform heating. In some embodiments of the present application, themain control circuit 123 controls switching or turning the switch 1231on when the no-smoking instruction is not received and the currentlocation is detected to not belong to first location information, andcontrols switching or turning the switch 1232 on when determining thatthe received output level of the connection circuit is a high level, andthe battery 124 supplies power to the cartridge 11 when both the switch1231 and the switch 1232 are switched or turned on. In some embodimentsof the present application, the main control circuit 123 controlsswitching or turning the switch 1231 on when the no-smoking instructionis not received and the current location is detected to not belong tofirst location information, and controls switching or turning the switch1232 on when determining that the received output level of theconnection circuit is a low level, and the battery 124 supplies power tothe cartridge 11 when both the switch 1231 and the switch 1232 areswitched or turned on.

The main control circuit 123 controls, using control pins of the switch1231 and the switch 1232, the switch 1231 and the switch 1232 to beswitched on or off. The switch 1231 remains switch-on by default. Whenreceiving the “no smoking” instruction, the main control circuit 123controls the switch 1231 to be switched from the switch-on state to theswitch-off state, that is, the electronic cigarette 10 is switched tothe “no smoking” mode. Even if the airflow sensor 121 detects theairflow and outputs a high level, that is, the user is vaping, the maincontrol circuit 123 switches the switch 1232 off according to a highlevel signal, and the battery 127 and the heating circuit 111 are stillin a switch-off state. In this case, the heating circuit 111 does notperform heating.

When the main control circuit 123 does not receive the “no smoking”instruction, the switch 1231 is in a switch-on state. When the airflowsensor 121 detects the airflow and outputs a high level, that is, whenthe user is vaping, the main control circuit 123 switches the switch1232 on according to the high level signal. In this case, because boththe switch is 1231 and the switch 1232 are switched on, the battery 127normally supplies power to the heating circuit 111, so that the heatingcircuit 111 heats the e-liquid, and the user can normally vape via theelectronic cigarette 10.

As shown in FIG. 7, when the intelligent terminal 201 and the electroniccigarette 10 leave the geofence 301 belonging to the non-smoking area,the intelligent terminal 201 automatically receives the notification of“leaving the fence” and sends an “allow smoking” instruction to theelectronic cigarette 10. The main control circuit 123 of the electroniccigarette 10 is switched to an “allow smoking” mode upon receiving the“allow smoking” instruction. That is, when the main control circuit 123is switched to the “allow smoking” mode, the airflow sensor 121 detectsthe airflow and outputs a high level, that is, it indicates that theuser is vaping, and the main control circuit 123 controls the heatingcircuit 111 to heat the e-liquid to vaporize the e-liquid.

Specifically, as shown in FIG. 8, the main control circuit 123 switchesthe switch 1231 from the switch-off state to the switch-on state uponreceiving the “allow smoking” instruction, that is, the electroniccigarette 10 is switched to the “allow smoking” mode. In this case, whenthe airflow sensor 121 detects the airflow and outputs a high level,that is, it indicates that the user is vaping normally, and the maincontrol circuit 123 switches the switch 1232 to the switch-on stateaccording to the high level signal. Because both the switch 1231 and theswitch 1232 are in the switch-on state, the battery 127 normallysupplies power to the heating circuit, so that the heating circuit 111heats the e-liquid to form a vaporized state, and the user can normallyvape via the electronic cigarette 10.

FIG. 9 is a schematic block diagram of an electronic cigarette 10according to some embodiments of the present application. A cigaretterod 12 further includes a positioning module 130. The positioning module130 is electrically connected to a main control circuit 123. Thepositioning module 130 has a locating or positioning function and isconfigured to obtain location or position information. The positioningmodule 130 is includes a Global Positioning System (GPS) positioningmodule, a BeiDou positioning module, a Global Navigation SatelliteSystem (GLONASS) positioning module, or the like.

In some embodiments of the present application, when a user carries theelectronic cigarette 10 as shown in FIG. 9 into a geofence 301, as shownin FIG. 10A, after the electronic cigarette 10 automatically receives,through the wireless communication circuit 125, a notification of“entering the fence” sent by the geofence 301, the main control circuit123 determines that a current location is within the geofence 301, thatis, after the current location belongs to non-smoking area information,a heating circuit 111 is prohibited from heating. Even if an airflowsensor 121 detects the airflow and outputs a high level, that is, whenthe user is vaping, the heating circuit 111 is not powered either, thatis, the heating circuit 111 cannot heat the e-liquid.

Referring back to FIG. 6, the switch 1231 remains in the switch-on stateby default. When determining that the current location is within thegeofence 301, that is, after the current location belongs to thenon-smoking area, the main control circuit 123 controls the switch 1231to be switched from the switch-on state to the switch-off state, thatis, the electronic cigarette 10 is switched to the “no smoking” mode.Even if the airflow sensor 121 detects the airflow and outputs a highlevel, that is, the user is vaping, the main control circuit 123 switchoff the switch 1232 according to a high level signal, and the battery127 and the heating circuit 111 are still in an open circuit state. Inthis case, the heating circuit 111 would not perform heating.

When determining that the current location is outside the geofence 301,that is, the current location does not belong to the non-smoking area,the main control circuit 123 maintains the switch 1231 in the switch-onstate. When the airflow sensor 121 detects the airflow and outputs ahigh level, that is, when the user is vaping, the main control circuit123 closes the switch 1232 according to the high level signal. In thiscase, because both the switch 1231 and the switch 1232 are switched on,the battery 127 is normally supplies power to the heating circuit 111,so that the heating circuit 111 heats the e-liquid, and the user cannormally vape via the electronic cigarette 10.

When the user carries the electronic cigarette 10 as shown in FIG. 9away from the geofence 301 belonging to the non-smoking area, as shownin FIG. 10B, after the electronic cigarette 10 automatically receives,through a wireless communication circuit 125, a notification of “leavingthe fence” sent by the geofence 301, the main control circuit 123 isswitched to an “allow smoking” mode. That is, when the main controlcircuit 123 is switched to the “allow smoking” mode, the airflow sensor121 detects the airflow and outputs a high level, that is, it indicatesthat the user can vape, and the main control circuit 123 controls theheating circuit 111 to heat the e-liquid to vaporize the e-liquid.

Referring back to FIG. 8, the main control circuit 123 switches theswitch 1231 from the switch-off state to the switch-on state uponreceiving the notification of “leaving the fence”, that is, theelectronic cigarette 10 is switched to the “allow smoking” mode. In thiscase, when the airflow sensor 121 detects the airflow and outputs a highlevel, that is, it indicates that the user can vape normally, the maincontrol circuit 123 switches the switch 1232 to the switch-on stateaccording to the high level signal. Because both the switch 1231 and theswitch 1232 are in the switch-on state, the battery 127 normallysupplies power to the heating circuit, so that the heating circuit 111heats the e-liquid to form the vaporization state, and the user cannormally vape via the electronic cigarette 10.

FIG. 11 is a flowchart of an operation method according to someembodiments of the present application. The operation method in FIG. 11is used for the electronic cigarette 10 in one or more of the foregoingembodiments.

In step 1101, the main control circuit 123 detects an output level of aconnection circuit. The connection circuit is a circuit for beingconnected to a cartridge 11. Because the cartridge 11 itself is providedwith resistance, when the cartridge 11 is inserted into the cigaretterod 12 and engaged with is the cigarette rod 12, the cartridge 11generates a divided voltage in the connection circuit. It may bedetermined, according to the output level of the connection circuit,whether the cartridge 11 is engaged with the cigarette rod 12.

In step 1102, it is determined whether the output level is a low level.If yes, go to step 1103; if no, indicating that the cartridge 11 is notengaged with the cigarette rod 12 and going back to step 1101, the maincontrol circuit 123 continuously detects the output level of theconnection circuit.

In step 1103, the main control circuit 123 drives an indicator light 126and a motor 122 to operate in an alerting mode. The alerting mode isthat: the indicator light 126 is turned on after the cartridge 11 isengaged with the cigarette rod 12, and gradually goes out; and the motor122 vibrates once after the cartridge 11 is engaged with the cigaretterod 12 for 0.5 s, with a vibration time of 40 ms. The alerting mode isnot limited thereto, which can be set according to practical conditions.In this way, the user can be reminded or informed that the cartridge 11has been engaged with the cigarette rod 12 to be used normally.

FIG. 12 is a flowchart of an operation method according to someembodiments of the present application. The operation method in FIG. 12may be used for the electronic cigarette 10 in one or more of theforegoing embodiments.

In step 1201, the main control circuit 123 detects whether the cartridge11 is engaged with the cigarette rod 12. If yes, go to step 1202; or ifno, continue performing the detection.

In step 1202, the main control circuit 123 obtains a vaping time T2 fromwhen the user takes a puff. Specifically, when the airflow sensor 121detects an airflow, the airflow sensor 121 outputs a high level, thatis, it indicates that the user is vaping, and in this case, the maincontrol circuit 123 controls a heating circuit 111 to perform heating tovaporize the e-liquid. When the airflow sensor 121 does not detect anairflow, the airflow sensor 121 outputs a low level, that is, itindicates that the user has stopped is vaping, and the main controlcircuit 123 controls the heating circuit 111 to stop heating. The maincontrol circuit 123 records a start time t2 at which the high level isgenerated when the low level is detected and changed to the high level,and records a start time t3 at which the low level is generated when thehigh level is detected and changed to the low level. The vaping timeT2=t3−t2 for which the user takes each puff, where t3 is greater thant2.

In step 1203, the main control circuit 123 detects whether the vapingtime T2 for which the user takes each puff is greater than a presetthreshold t4. If yes, go to step 1204. If no, go to step 1205 to keepthe number C1 of vaping puffs unchanged.

In step 1204, add 1 to the number C1 of vaping puffs. In step 1205, keepthe number C1 of vaping puffs unchanged.

In step 1206, the main control circuit 123 determines whether the numberC1 of vaping puffs within a vaping time T3 is greater than a presetthreshold n. If C1 is greater than n, go to step 1207; or if C1 is lessthan n, go back to step 1202.

In step 1207, the main control circuit 123 drives a motor 122 to operatein an alerting mode. The alerting mode is: the motor 122 vibrates once,and a vibration time is 40 ms. The alerting mode is not limited thereto.In this way, the alerting mode may be configured to remind or inform auser to control the vaping amount to prevent excessive smoking.

FIG. 13 is a flowchart of an operation method according to someembodiments of the present application. The operation method in FIG. 13may be used for the electronic cigarette 10 in one or more of theforegoing embodiments.

In step 1301, the main control circuit 123 obtains an acceleration valueof the acceleration sensor 129. The acceleration value may include atleast one of an acceleration value in an X-axis direction, anacceleration value in a Y-axis direction, or an acceleration value in aZ-axis direction in a is coordinate system. The acceleration sensor 129is a G-sensor (a gravity sensor), but is not limited thereto.

In step 1302, the main control circuit 123 determines whether theobtained acceleration value is greater than a preset threshold. If yes,it indicates that the user is shaking the cigarette rod 12, and proceedsto step 1303; or if no, goes back to step 1301.

In step 1303, the main control circuit 123 enables the wirelesscommunication circuit 125 to transmit a wireless signal, and drives theindicator light 126 to operate in the alerting mode.

Specifically, the wireless communication circuit 125 may include theBluetooth module, and the main control circuit 123 enables the Bluetoothmodule when performing wireless communication by using the Bluetoothmodule and when the obtained acceleration value is greater than thepreset threshold, and sends or transmits the broadcast signal throughthe Bluetooth module. In addition, a third alerting mode is when theindicator light 126 flashes for 15 times, to remind the user that aBluetooth mode of an electronic cigarette 10 is enabled. In addition, ifthe user performs the shaking action again, the indicator light 126 willflash again for 15 times.

Insome embodiments, the top ends of the magnet 1631 and the magnet 1632are slightly higher than a cap face of the battery holder cap 161. Themagnet 1631 and the magnet 1632 are configured to attract the cartridge11 and the cigarette rod 12 through a magnetic force when the cartridge11 and the cigarette rod 12 are engaged, so that the cartridge 11 or thecigarette rod 12 can be prevented from sliding when the user vapes viathe electronic cigarette 10, thereby improving user experience. Inaddition, the through hole 1614 is configured to communicate an airflowdetection mouth or hole of an airflow sensor 121 inside the cigaretterod 12 with external space.

After the battery holder cover 161 covers an upper end portion of thebattery holder 169, the pogo pin 1621, the pogo pin 1622, and the pogopin 1623 may be in contact with the contact pad 1511, the contact pad1512, and the contact pad 1513 respectively at the lower end portion ofthe PCB is module 151 in the cartridge 11, so that the pogo pin 1621,the pogo pin 1622, and the pogo pin 1623 are all electrically connectedto a main control module 166. The main control module 166, the battery127, the charging circuit 128, the motor 122, and the airflow sensor 121are all installed in a corresponding structure in the battery holder169, and the battery 127, the charging circuit 128, the motor 122, andthe airflow sensor 121 are all electrically connected to the maincontrol module 166.

In some embodiments of the present application, the cigarette rod 12further includes a silicone sleeve 167. The silicone sleeve 167 isconfigured to protect the airflow sensor 121. The cigarette rod 12further includes a light guide bar holder 165. The light guide barholder 165 is disposed on the battery holder 169 and is located at oneside of the main control module 166. An indicator light 126 is disposedon the main control module 166 and is located between the main controlmodule 166 and the light guide bar holder 165. When the indicator light124 is on, light information may be displayed to the user through thelight guide bar holder 165 and the through hole in a housing 171.

In some embodiments of the present application, the battery 128 islocated between the main control module 166 and the charging circuit128. The charging circuit 128 is fixed to the battery holder 169 usingscrews 168. The cigarette rod 12 further includes the antenna 170 forreceiving and transmitting the wireless signal. The antenna 170 isdisposed between one side of the battery 127 and the housing 171, andthe antenna 170 is electrically connected to the main control module166. In some embodiments of the present application, the cigarette rod12 further includes a sponge pad 164, the sponge pad 164 is disposedbetween the other side of the battery 127 opposite the antenna 170 andthe housing 171. The sponge pad 164 is in contact with the battery 127and an inner wall of the housing 171 to provide a cushioning force. Whenthe cartridge 11 is engaged with the cigarette rod 12, the accommodatingspace in the housing 171 accommodates a lower tube 1432 and a bottom cap154 in the cartridge 11.

In some embodiments of the present application, when the cartridge 11 isnot engaged with the cigarette rod 12, the through hole 1614 forventilation of the battery holder cap 161 in the cigarette rod 12 mayenable outside air to be in communication with the airflow detectionthrough hole of the airflow sensor 121.

FIG. 24 is a schematic structural diagram of an airflow channel of theelectronic cigarette 10 according to some embodiments of the presentapplication. As shown in FIG. 24, when the cartridge 11 is engaged withthe cigarette rod 12, there is a gap between an outer side wall of alower tube body 1432 of the cartridge 11 and an inner side wall of ahousing 171 of the cigarette rod 12, and there is also a gap forventilation between a bottom cap 154 of the cartridge 11 and a batteryholder cap 161 of the cigarette rod 12. The airflow enters an airflowdetection through hole of an airflow sensor 121 through the through hole1614 for air circulation of the battery holder cap 161, to form anairflow channel f1 for communicating outside air of the electroniccigarette 10 with the airflow sensor 121 of the electronic cigarette. Inthis way, the outside air of the electronic cigarette 10 can effectivelyenter.

When the cartridge 11 of the electronic cigarette 10 is engaged with thecigarette rod 12, when the user performs a vaping action, the airflow atthe airflow detection through hole of the airflow sensor 121 passesthrough the through hole 1614 at the battery holder cap 161 to enter thegap between the bottom cap 154 and the battery holder cap 161, that is,the air flow is detected, the air flow changes, and a high level isoutput. A main control module 166 enables the battery 12 to supply powerto the heating component 146, and the heating component 146 heats thee-liquid. Then, air enters the space between the heating component 146and the tar absorbing pad 419 through the air tube 152 and the throughhole 1504. At this time, some e-liquid is vaporized by heating, and theairflow brings smoke formed by vaporizing the e-liquid into the airflowchannel 1433 through the side end opening 1505, and the smoke enters theuser's mouth through corresponding through holes on the upper tube 1431and a vaping is cap 142, thereby forming the airflow channel f2 toachieve a smoking action. It should be noted that during a vapingprocess, the air also enters the air tube 152 through the airflowchannel f1.

In some embodiments of the present application, referring back to FIG.2A, when the cartridge 11 is not inserted into the cigarette rod 12,there is no load between the pogo pin 1621 and the pogo pin 1622, andthe main control module 166 detects that a high level exists between thepogo pin 1621 and the pogo pin 1622. As shown in FIG. 2B, when thecartridge 11 is inserted into the cigarette rod 12, the pogo pin 1621and the pogo pin 1622 are electrically connected to the contact pad ofthe PCB module 151, that is, a current loop is formed between the PCBmodule 151 as a load and the pogo pin 1621 and the pogo pin 1622. Inthis case, because the PCB module 151 as a load may divide a voltage,the main control module 166 detects that a low level exists between thepogo pin 1621 and the pogo pin 1622, and the main control module 166drives the indicator light 126 and the motor 122 to operate in thealerting mode. The alerting mode is: the indicator light 126 is turnedon after the cartridge 11 and the cigarette rod 12 are engaged, andgradually goes out; and after the cartridge 11 and the cigarette rod 12vibrates once after being engaged for 0.5 s, with a vibration time of 40ms. The alerting mode is not limited thereto, which can be set accordingto practical conditions. In this way, the user can be reminded andinformed that the cartridge 11 and the cigarette rod 12 have beenengaged and can be used normally. In some embodiments of the presentapplication, the main control module 166 may also determine that thecartridge 11 and the cigarette rod 12 have not been engaged when anoutput level of the connection circuit formed by the pogo pin 1621 andthe pogo pin 1622 of the cigarette rod 12 is detected to be a low level,and determine that the cartridge 11 and the cigarette rod 12 have beenengaged when the output level of the connection circuit is detected tobe a high level.

When the user determines, according to the indicator light 126 and themotor 122, that the electronic cigarette 11 has been engaged, the usermay start a normal vaping action.

When the user does not perform an inhalation or vaping action, the isairflow sensor 121 does not detect the airflow change, and the airflowsensor 121 outputs a low level. When the user performs the inhalation orvaping action, the airflow sensor 121 detects the airflow, and theoutput level of the airflow sensor 121 changes from a low level to ahigh level. The main control module 166 outputs a voltage through thepogo pin 1621 and the pogo pin 1622 when receiving a signal indicatingthat the output level of the airflow sensor 121 changes from a low levelto a high level, and provides the output voltage to the heatingcomponent 146 via the contact pad of the PCB module 151, the elasticpiece 1481, the elastic piece 1482, the pin 1471, and the pin 1472, sothat the heating component 146 performs heating, and the e-liquid incontact with the heating component 146 is vaporized. In addition, whenthe user vapes, air enters the cartridge 11 through the air tube 152,and the smoke in the vaporized state is fed to the user's mouth throughthe airflow channel, thereby completing an action of smoking once. Whenthe smoking action is stopped, the airflow change in the electroniccigarette 10 stops, the airflow sensor 121 does not detect an airflowchange, and the output level of the airflow sensor 121 changes from ahigh level to a low level. In this case, the main control module 166controls disconnecting the output voltage between the pogo pin 1621 andthe pogo pin 1622 after obtaining the signal indicating that the outputlevel changes from the high level to the low level, that is, the heatingcomponent 146 stops heating. The main control module 166 records a starttime t2 at which the high level is generated when the output level ofthe airflow sensor 121 is detected to change from the low level to thehigh level, and records a start time t3 at which the low level isgenerated when the output level of the airflow sensor 121 is detected tochange from the high level to the low level next time. A time T2=t3−t2for which the user takes one puff, where t3 is greater than t2. The maincontrol module 166 performs counting and increases a count value C1 whenT2 is greater than a preset threshold t4, for example, may increase thecount value by 1. t4 may be set to 1 s, but is not limited thereto. Ifthe user keeps performing the vaping action, when the count value C1within time T3 is greater than a preset is threshold n, the main controlmodule 166 drives the motor 122 to operate in the alerting mode. Thealerting mode is: the motor 122 vibrates. For example, when the countvalue C1 is greater than 15 within 10 minutes of T3, the main controlmodule 166 may drive the motor 122 to vibrate once for a short time forone second after the 15th puff with a vibration time of 40 ms, therebyeffectively alerting the user to control the vaping amount and preventexcessive vaping.

In some embodiments of the present application, the airflow sensor 121may also output a low level when the airflow is detected, and outputs ahigh level when no airflow is detected. The main control module 166 maydetermine whether the user is smoking according to the level informationthat has different logic levels and output by the airflow sensor 121,and a specific determining manner is not limited to the foregoing.

In some embodiments of the present application, the main control module166 stops the power supply of the battery 127 to the heating component146 when T2 is greater than t5, so that the heating component 146 stopsbeing heated. For example, the main control module 166 stops the powersupply of the battery 127 to the heating component 146 when T2 isgreater than 5 s, so that the heating component 146 stops being heated.In this way, the user can be prevented from smoking excessively.

In some embodiments of the present application, after the cartridge 11and the cigarette rod 12 are engaged, the main control module 166detects data information of the authentication circuit 112 electricallyconnected to the pogo pin 1623 in the PCB module 151. In someembodiments, the authentication circuit 112 includes a resistor thatindicates flavor information of the cartridge 11, that is, differentresistance values correspond to different flavors of the cartridge. Forexample, when the resistance is 2 ohms, it indicates that the cartridge11 with a grapefruit-flavor is engaged with the cigarette rod 12. Whenthe resistance is 4 ohms, it indicates that the cartridge 11 with amint-flavor is engaged with the cigarette rod 12. It should be notedthat a resistance value of a specific resistor and the flavor of thecorresponding cartridge 11 are not limited is thereto, which can bedetermined according to practical conditions. When the main controlmodule 166 detects that the resistance of the resistor connected to thepogo pin 1623 is 2 ohms, it indicates that the cartridge 11 is thecartridge with a grapefruit-flavor.

In some embodiments of the present application, the authenticationcircuit 112 includes an encryption chip (not shown in the figure). Theencryption chip stores encrypted data information of the cartridge 11,the data information including a unique ID number, a flavor of thecartridge, an amount of tar of the cartridge, and the like. The maincontrol module 166 includes a decryption module corresponding to theencryption chip, and the decryption module includes a decryption chip.The decryption module is configured to decrypt the encrypted informationwhen the cartridge 11 and the cigarette rod 12 are in the engaged state,send or transmitting decryption success information when the decryptionis successful, and transmit decryption failure information when thedecryption fails. After the decryption success information is received,the main control module 166 supplies power to the main control module166 between the battery 127 and the heating circuit 111 to drive theindicator light 126 to flash three times and drive the motor 123 tovibrate for a short time three times. The main control module 166enables a Bluetooth mode and transmits a broadcast signal by the antenna170 after successfully decrypting the encrypted data informationobtained from the encryption chip.

In some embodiments of the present application, the main control module166 does not respond to changes in voltage or current between the pogopin 1621 and the pogo pin 1622 upon receiving the decryption failureinformation. In some embodiments of the present application, the maincontrol module 166 responds to changes in voltage or current between thepogo pin 1621 and the pogo pin 1622 upon receiving the decryptionsuccess information. In some embodiments of the present application, themain control module 166 does not respond to level information output bythe airflow sensor 121 upon receiving the decryption failureinformation. In some embodiments of the present application, the maincontrol module 166 responds to level information output by the airflowsensor 121 upon receiving the decryption success information.

In some embodiments of the present application, the main control module166 obtains an acceleration value of an acceleration sensor 129, anddetermines a downtilt angle of the cartridge 11 according to theobtained acceleration value. As shown in FIG. 18, when the electroniccigarette 10 is placed horizontally, that is, the electronic cigarette10 as shown in the state A. A downtilt angle determined by the maincontrol module 166 is 0°, and in this case, the main control module 166does not output any action instruction. When the electronic cigarette 10is placed obliquely and a mouthpiece 141 is inclined downward, the maincontrol module 166 determines that the downtilt angle is not less than apreset threshold α. α may be set to 20° and is saved or stored in amemory 124, but is not limited thereto. For the electronic cigarette 10in the state B in FIG. 18, when the user vapes via the electroniccigarette 10 and tilts the mouthpiece 141 downward, it may be determinedthat the user is vaping via the electronic cigarette 10 in an inversedmanner. However, because the mouthpiece 141 of the electronic cigarette10 being inclined downward causes the e-liquid in the storagecompartment 1434 not to penetrate into the heating component 146 throughthe heat-conducting top cap 144 and the heat-conducting silica gel 145as a result of gravity influence. Therefore, when the user vapes theelectronic cigarette in an inversed manner for too long, the e-liquid inthe heating component 146 is dried out, causing the dry burning of theheating component 146 with a burnt flavor.

Therefore, when the electronic cigarette 10 is placed obliquely and themouthpiece 141 is tilted downward, the main control module 166determines that the downtilt angle is not less than a preset thresholda, and also detects that the output level of the airflow sensor 121 is ahigh level. In addition, when a vaping time T2 is greater than thepreset threshold t4, the main control module 166 drives the motor 122 tovibrate in a fourth driving mode. The fourth driving mode is: drivingthe motor 122 to vibrate three is times, a vibration time being 40 mseach time. Therefore, the user is alerted or informed to avoid the burntflavor generated by the dry burning of the heating component 146 causedby excessively long vaping time inversely, thereby improving userexperience. In some embodiments of the present application, the tiltangle determined by the main control module 166 may be a positive valueor a negative value, the positive value and the negative value beingused to indicate different downtilt directions. The positive valueindicates that the mouthpiece 141 is tilted down, which is an inversevaping state; and the negative value indicates that the mouthpiece 141is tilted up, which is a normal use state.

In some embodiments of the present application, the main control module166 enables the wireless communication function when the accelerationvalue of the acceleration sensor 129 is detected to be greater than thepreset threshold al, that is, transmits the broadcast signal by theantenna 170. The wireless communication function may be a Bluetoothfunction, and the antenna 170 may be a Bluetooth antenna, but is notlimited thereto, as described above, which may be selected according toa specific situation. In addition, the main control module 166 drivesthe indicator light 126 in a third driving mode, the third driving modebeing that the indicator light 126 flashes 15 times, to remind the userthat the Bluetooth mode of the electronic cigarette 10 has been enabled.In addition, if the acceleration value is detected to be greater thanthe preset threshold value again within the preset time, that is, theuser performs the shaking action again, the main control module 166continues to drive the indicator light in the third driving mode. Afterthe user learns that the Bluetooth mode of the electronic cigarette 10is enabled, the user may perform Bluetooth matching with the electroniccigarette via a mobile phone to obtain the user smoking information andrelated data information of the cartridge 11 of the electronic cigarette10.
